摘要: A denture base lining material to be used upon mixing a liquid component and a powder component is disclosed, characterized in that the liquid component comprises a phthalic ester-based plasticizer and containing from 5 to 15% by weight of ethyl alcohol and from 5 to 20% by weight of a liquid paraffin or squalane alone or a mixed solution thereof, and the powder component comprises a powder comprising any one of the following powders (a), (b), or (c), or a mixture of two or more thereof: (a) an ethyl methacrylate polymer powder containing from 1 to 5% by weight of a phthalic ester-based plasticizer; (b) a copolymer powder represented by the following formula: ##STR1## wherein n/(m+n) is from 0.15 to 0.55, and containing from 0.5 to 2% by weight of a phthalic ester-based plasticizer; and (c) a mixed powder comprising a polyethyl methacrylate powder having a copolymer powder represented by the following formula mixed therewith: ##STR2## wherein n/(m+n) is from 0.45 to 0.76. The denture base lining material according to the present invention is low in the rate of change in elastic strain, is less found in the sticky feeling, and can be readily peeled apart from the denture after the use.
